Bauxite ore is one of the primary source of aluminum but it must first be chemically processed to produce alumina (aluminum oxide). The next step of aluminum production is smelting of alumina using an electrolysis process (Hall-Heroult process). This electrolysis process is driven by electrical current. Electrolyte (molten salt) with immersed carbon anodes is used in order to dissolve the alumina. Carbon anodes are carrying electrical current and thee chemical bond between aluminum and oxygen in the alumina is broken.

How do trees act as carbon sinks?
Romashka [77]


The best answer is D.

A carbon sink is anything that absorbs more carbon than it produces or releases.

The main carbon sinks found in nature are plants, the ocean and soil.  Plants such as trees capture carbon dioxide from the atmosphere and use it in photosynthesis. Part of this carbon is transferred to soil as the trees and other plants die and decompose.

Due to the effectiveness of trees and other plants as carbon sinks,  the Kyoto protocol proposed that emission reduction can be achieved through absorption of carbon dioxide by these plants.

<span>Streptococcus is a genus of coccus (spherical) Gram-positive bacteria belonging to the phylum Firmicutes[3] and the order Lactobacillales (lactic acid bacteria). Cell division in this genus occurs along a single axis in these bacteria, thus they grow in chains or pairs, hence the name—from Greekstreptos, meaning easily bent or twisted, like a chain (twisted chain). Contrast this with staphylococci, which divide along multiple axes and generate grape-like clusters of cells.)</span>

FromTheMoon [43]

Answer:

spiders are.   generally ectotherms.Their internal temperature depends on external temperature transfer.They are also poikilothermic because the body temperature varies with that of the external environment.,

In animals, individual cells are grouped into  tissues. e,g Blood. The tissues gives rise to organs.

A main function of most types of epithelial tissue is covering surfaces.They line major all hollow surfaces, and covering body surfaces.

Resorption id the movement of fluid from the glomerular filtrate back into the blood. Ions, glucose,and other escaped metabolites are returned to the blood stream.

In humans, goosebumps are a vestige of a mammalian adaptation to thermoregulation. This is a thermoregulatory mechanism to regulate the body temperature,Goosebumps emits heat,  to turn the moisture from the skin  to vapour. This evaporate to release this moisture, which cools the body.
